The expected coronation of Team USA in Pool B didn't happen on Tuesday night, as Italy pulled off a stunning upset of the tournament favorites.

Instead, Italy (3-0) will play Mexico (2-1) to determine the Pool B winner while Team USA (3-1) is idle and hopes either Italy wins (which would earn the Italians the pool win and the runner-up U.S. a spot in the quarterfinals), or the final score provides a favorable tiebreaker as a Mexico victory sets up a three-way tie atop Pool B.

It will be an intriguing matchup with three nation's World Baseball Classic hopes hanging in the balance.
